Boris-Barboris Posted January 26, 2016 Share Posted January 26, 2016 (edited) Download and source (MIT license):https://github.com/Boris-Barboris/CorrectCoL/releases https://spacedock.info/mod/789/CorrectCoL Stockalike CoL indicator for stock Aerodynamics, accounts not only for ILiftProviders. Please, don't try it with FAR (mod disables itself if FAR is found). Simple static stability analysis: Most graphs are torque-AoA relations: green graph - current fuel levels.yellow graph - emptyed fuel tanks. Exceptions:blue graph - pitch L/D ratio (wet).blue vertical line - level flight AoA (wet). aoa range - AoA and sideslip range to plot, degrees.aoa marks - horizontal axis marks step, degrees.aoa compress - zero for 1:1 AoA axis, positive for quadratic compression. Helps to focus on important stuff near zero AoA while not loosing large-AoA behaviour. speed - speed towards root part nose direction, m/s. Enter negative values to analyze retrograde stability. altitude - meters above sea level. Four simplistic and quite stupid trait labels, may sometimes fool you. Be careful with launch clamps, they are accounted for too. Also, move your craft by the root part a little after loading to ensure correct results for graph (strange API stuff).

Joco223 Posted January 26, 2016 Share Posted January 26, 2016 Very nice mod It's going to be very useful for building SSTO's Link to comment Share on other sites More sharing options...
Stone Blue Posted January 26, 2016 Share Posted January 26, 2016 OK... whats the difference between this and stock? What's it do different? Link to comment Share on other sites More sharing options...

Stock CoL indicator only accounts for stuff like wings, control surfaces and plane (mk2, mk3) fusalage parts. Most of the time, it's enough to eyeball stability, but sometimes it's not. Strap up Mk1 cockpit + a couple of cylindrical LF tanks in stock editor, no wings, nothing more, look at CoL. Then compare to modded.

Stone Blue Posted January 26, 2016 Share Posted January 26, 2016 So this takes into consideration, ALL parts?... where stock only looks at parts that are supposedly "designed" to provide lift?.. Probably such as only those listed as being in the aero catagory? Link to comment Share on other sites More sharing options...
Boris-Barboris Posted January 26, 2016 Author Share Posted January 26, 2016 Just now, Stone Blue said: where stock only looks at parts that are supposedly "designed" to provide lift Their full description panel (right-click on part icon) contains things like LiftingSurface or ControlSurface with parameters like LiftRating etc. Link to comment Share on other sites More sharing options...
smjjames Posted January 26, 2016 Share Posted January 26, 2016 (edited) This is definetly neat. One probable issue though, how come there's a tilt with the same craft in both editors? Edit: I looked at the stock crafts and those are fine, but when I remove all lifting surfaces, that tilt appears. Is it supposed to do that?

Tilt is from increased AoA offset from stock 1 degree to 5, so it's okay to be more tilted. Imagine, that SPH and VAB is an aerodynamic tube, like on a pic: alpha-zero is 3 degrees now, redownload zip from github (shamefully replaced it), if you want 3. Fixed bug with ModuleLiftingSurfaces, only true lift component from them is now taken (orthogonal to airstream).

Besides, you don't need it with FAR, it has it's own indicator. Link to comment Share on other sites More sharing options...

Boris-Barboris Posted April 19, 2016 Author Share Posted April 19, 2016 v1.3 build is up. Fixed bug with incorrect parachutes drag. Added L/D for pitch and simple level flight AoA indicator (blue vertical line). Link to comment Share on other sites More sharing options...
Skalou Posted April 19, 2016 Share Posted April 19, 2016 really good mod thank you! some ideas of suggest: add some sliders, </> or -/+ buttons aside the textbox for the speed and altitude, for watching faster what could happen during a flight.

vardicd Posted July 2, 2016 Share Posted July 2, 2016 I would love to use a mod like this to help me build better planes and such, but... I'm an idiot, and have no idea how to read a graph like this. it's all meaningless gibberish to me. Link to comment Share on other sites More sharing options...
gilflo Posted July 4, 2016 Share Posted July 4, 2016 (edited) Hello Usefulll mod but I have an issue in the VAB: The direction of the COL is always perpendicular whatever you build. COL direction is ok (down) when mod is removed. Look this pic: COL is above COM, because we have a big tank you don't see under the lander, but the direction is not good....

SkyKaptn Posted July 4, 2016 Share Posted July 4, 2016 I am not too sure what to make of this. The aircraft flies quite stable with almost 0 AoA wet to dry. But the graph tells me it is partially stable. Link to comment Share on other sites More sharing options...
